Synopsis

unimorph inflect [OPTIONS] <LEMMA>

Description

Given a lemma (dictionary form), returns all its inflected forms with their morphological features. This is the primary way to see a word's full paradigm.

Arguments

Argument	Description
`<LEMMA>`	The lemma (dictionary form) to look up

Options

Option	Description
`-l, --lang <LANG>`	Language code (ISO 639-3)
`-f, --features <PATTERN>`	Filter by feature pattern (e.g., `V;IND;*;SG`)
`--json`	Output as JSON
`--tsv`	Output as TSV (tab-separated, no headers)

Examples

Basic Lookup

unimorph inflect -l heb כתב

LEMMA        FORM         FEATURES
------------------------------------------------------------
כתב         אכתוב       V;1;SG;FUT
כתב         יכתבו       V;3;PL;FUT;MASC
כתב         יכתוב       V;3;SG;FUT;MASC
כתב         כותב        V;SG;PRS;MASC
כתב         כתב         V;3;SG;PST;MASC
...

29 form(s) found.

Filter by Features

Use wildcards (*) to match any value at a position:

# Only singular forms
unimorph inflect -l heb כתב -f "V;*;SG;*"

# Only past tense
unimorph inflect -l heb כתב -f "V;*;*;PST;*"

JSON Output

unimorph inflect -l heb כתב --json

[
  {
    "lemma": "כתב",
    "form": "אכתוב",
    "features": {
      "raw": "V;1;SG;FUT",
      "features": ["V", "1", "SG", "FUT"]
    }
  },
  ...
]

TSV for Piping

unimorph inflect -l heb כתב --tsv

כתב	אכתוב	V;1;SG;FUT
כתב	יכתבו	V;3;PL;FUT;MASC
כתב	יכתוב	V;3;SG;FUT;MASC
...

Scripting Examples

# Get unique forms only
unimorph inflect -l heb כתב --tsv | cut -f2 | sort -u

# Count forms by tense
unimorph inflect -l heb כתב --tsv | cut -f3 | grep -o 'PST\|PRS\|FUT' | sort | uniq -c

# Find forms matching a pattern
unimorph inflect -l spa hablar --tsv | grep "1;SG"

Notes

The lemma must match exactly (case-sensitive for most languages)
Use search with --lemma for partial/wildcard matching
Returns empty results if the lemma doesn't exist in the dataset
